Apex Dynamics supplier in Romania
precision planetary gearboxes (servo gearboxes)
Founded in 1987 · Headquarters: Taichung, Taiwan
Who is Apex Dynamics and what does it make?
Apex Dynamics is a manufacturer of precision planetary gearboxes, based in Taichung, Taiwan, founded in April 1987; the subsidiary Apex Dynamics USA, in Ronkonkoma, New York, coordinates marketing and support for North America. The range covers inline planetary gearboxes (PAII, PGII, PSII, PNII series), right-angle gearboxes with hypoid gearing (KH, KF series) and spiral bevel pinion gearboxes (AT series), all designed for direct coupling to servomotors in industrial automation. From this range we can quote the inline and right-angle versions for retrofitting production lines in Romania.
What sets Apex Dynamics gearboxes apart is the low-backlash output construction, designed for the positioning loop of a servomotor, not for a generic industrial transmission. The PGII inline series comes in several flange sizes, suited to packaging machines or Cartesian robots, while the KH and KF right-angle series allow the motor to be mounted perpendicular to the driven shaft, where installation space is limited. The AT series spiral bevel gearboxes are a separate family, with spiral bevel gearing, listed separately from the planetary range.
For the Romanian market, Apex Dynamics makes sense for retrofitting machines where a servomotor has to be coupled through a low-backlash gearbox — Cartesian robots, positioning tables, linear modules on packaging lines. Integrators choose the gearbox by flange and ratio, and we confirm compatibility before the quotation.
What do we supply from the Apex Dynamics range?
| Product | Description |
|---|---|
| PGII Series Inline Planetary Gearboxes | Inline planetary gearbox from the base Apex Dynamics family, with proven low-backlash gearing, designed for direct coupling on the shaft of a servomotor. Available in several flange sizes and ratios, which allows a model close to the gearbox already fitted to be chosen in a retrofit. Typical application: positioning axes on packaging machines, Cartesian robots and linear modules, where accuracy depends directly on the angular backlash of the gearbox. |
| KH/KF Series Hypoid Right-Angle Gearboxes | Gearboxes with output perpendicular to the input shaft, with hypoid gearing (the KH series is a high-precision hypoid gearbox), useful where the mounting space does not allow the servomotor to be aligned with the driven shaft. The right-angle housing shortens the overall length of the motor-gearbox assembly. Frequently found on short conveyors, rotary positioning tables and mechanisms where the motor must be mounted sideways or vertically relative to the load. |
| AT Series Spiral Bevel Pinion Gearboxes | A separate family, with spiral bevel gearing in place of the planetary stage. The AT series includes, among others, the AT-FC, AT-FH and AT-4M versions. |
Why Apex Dynamics?
- Low-backlash output construction, dedicated to direct coupling to servomotors, not to industrial transmissions with high backlash
- Three design families — inline, right-angle and spiral bevel pinion — cover most mounting configurations in automation
- ISO 9001 certified manufacturing, with CE and ATEX variants for installations requiring explicit conformity
- Wide range of flanges and ratios on each series, useful when replacing a worn gearbox without redesigning the shaft

How do we supply Apex Dynamics in Romania?
For Apex Dynamics we rely on the manufacturer's technical documentation; availability and lead time are confirmed in the quotation. Apex Dynamics planetary gearboxes reach us to order, through supply channels in the USA and Taiwan; this range is not held on the shelf but brought in to order, usually in 1–4 weeks. For a quotation we need the exact series code — PGII, KH or AT-FC, for example —, the flange size, the ratio and the diameter of the servomotor shaft on which the gearbox is mounted. We do not promise permanent availability and recommend confirming the real lead time before passing it on to the end customer.
For installations in Romania, we check urgent availability for each request, and warranty service remains the responsibility of the plant in Taiwan.
Frequently asked questions about Apex Dynamics
What does Apex Dynamics make?
Apex Dynamics manufactures precision planetary gearboxes for direct coupling to servomotors, in three design families: inline, right-angle and spiral bevel pinion. The manufacturer, based in Taichung, Taiwan (with its American subsidiary in Ronkonkoma, New York), relies on low angular backlash and on numerous flange types and ratios, useful above all in retrofitting positioning axes on automation lines.
How do I choose an Apex Dynamics gearbox by code?
Start from the series already fitted on the machine — for example PGII, KH or AT-FC — then confirm the flange size, the ratio and the diameter of the servomotor shaft. These three elements practically identify the model in the manufacturer's catalogues. If the gearbox is old and the code is no longer clearly legible, a photo of the nameplate and the flange dimensions help us find the equivalent variant.
Do you supply Apex Dynamics gearboxes in Romania and within what lead time?
Yes, to order, through supply channels in the USA and Taiwan; the lead time is usually 1–4 weeks from order confirmation, depending on availability at the manufacturer. This range is not held on the shelf, so we recommend checking the exact lead time before promising a final delivery date to the end customer.
What do I send for an Apex Dynamics gearbox quotation?
The series code from the nameplate of the gearbox or of the machine on which it is fitted, the flange size, the ratio wanted and the servomotor shaft diameter. If the existing gearbox is worn, photos of the nameplate and of the installation are also useful, so that we can confirm the exact equivalent before preparing the quotation.
What is the difference between the inline and right-angle series at Apex Dynamics?
The inline series (PGII, PAII, PNII) has the gearbox output on the same axis as the input from the servomotor, a typical mounting for linear axes and positioning modules. The right-angle series (KH, KF) moves the output to 90 degrees relative to the motor, useful when the mounting space does not allow the servomotor to be aligned directly with the driven load.
How do I request a Apex Dynamics quotation?
Send the Apex Dynamics code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
